CNC machining of stainless steel pneumatic valves typically requires the use of CNC milling machines, CNC lathes, and drilling machines. Specific processes include milling, turning, drilling, and thread machining to precisely manufacture the valve's components and apertures.

Various methods can be used for surface treatment of stainless steel pneumatic valves to enhance their corrosion resistance, wear resistance, and appearance. Common surface treatment methods include sandblasting, polishing, plating, and coating. Sandblasting removes oxide layers and dirt from the surface, polishing improves surface smoothness and brightness, plating increases corrosion resistance, and coating provides a protective layer to prevent corrosion and oxidation.

CNC machining of stainless steel pneumatic valves enables high precision and complex shaping, ensuring the valves meet design requirements in terms of quality and performance. Surface treatment methods enhance the durability and aesthetics of the valves, extending their service life. The specific process flow may vary depending on the design requirements and specifications of the valves.
